Currently, detection of the emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae), consists of visual inspection and identification of characteristic damage and/or beetles. The objective of this study is to develop a trap and a semiochemical lure system for EAB. In summer, 2003, a panel trap design was employed to test four colors simultaneously. Over 500 beetles were caught in a three week period, with more beetles being caught on purple traps than on any other color. We are currently performing several studies to observe the effects of color and design on trap catch. This work will be discussed in detail.
